Can Wrought Iron Fence be Welded Together for High Security Applications?

While a large majority of iron fence applications are installed using brackets and screws, high-security applications may require a more tamper-proof installation. The best way for a highly secure iron fence is to forgo the brackets and weld the iron fence panels right to the steel posts.

Below is a photo of of how our Stronghold Iron fence panels are normally connected to the post with our cast iron bracket and self-tapping screw:

While that type of installation works perfectly fine in 99% of installations, if the fence is being installed for security reasons this can be a weak point. A person with a socket wrench could undo the screw and take the panel down.

There are two ways that a little welding can make an iron fence one of the best security fences you can buy.

WELDING OPTION #1 – Full Rail-to-Post Weld

This option is going to completely take the bracket and screw out of the equation and have you welding the fence panel rail directly to the posts. The iron railings are 1/8in thick. The posts are typically have a 14ga wall until you get into the larger driveway gate posts in the 4in and 6in sizes that are 7ga wall thickness.

The great thing about this method is that you are joining the fence panel to the rail permanently. The entire system is tied together permanently. Unless someone is going to cut a hole in the fence, there is no tampering with the fence and its very secure.

The downside to this method is that you need a skilled welder to do it (if you are not one). You also have to sand off the protective powder coating and galvanization for a clean metal-to-metal weld. So extra care needs to be taken to use a galvanizing primer and rust inhibiting paint to coat those welded areas.

WELDING OPTION #2 – Simple Tack Weld from Screw to Bracket

This option requires less welding skill and less exposed metal. For this setup, you will still use the bracket and screw to install the fence panel to the post like the image shown earlier in the article. However, this time you will only put a simple tack weld (sometimes called a booger weld) from the screw to bracket. This will join those two pieces and prevent someone from putting a socket over the screw head and backing it out.

This is a much easier way to secure the fence without professional welding knowledge. You just need a small bare metal spot on both pieces and a simple tack weld. The touch-up on the finish is much more minimal too.

The downside is that its not as strong as a full welded connection and still requires a welder (or basic welding knowledge).

Hopefully that helps out if you are looking for a security fence.

I've been working in the fence industry since 2009 with a wide array of installation, sales and marketing experience. I've had lots of experience with different types of iron and aluminum fence and gate installations. Generally a 'DIY' kind of guy when it comes to a wide array of projects.
